What it is

The Westward 22YM05 is an analog battery tester designed for 12V and 6V lead-acid batteries. It applies a resistive load up to 100 amperes to measure cold-cranking performance between 200 and 1,000 amperes. The unit operates from 0 to 16 volts DC and requires no internal batteries for the tester itself.

Who it suits

Technicians and DIY users who need a simple, immediate indication of starting power on conventional automotive batteries will find it fit for purpose. Shops that require digital data logging, alternator ripple tests, or support for lithium chemistries should look at a different class of instrument.

Sustained behaviour

The low-resistance load circuit draws high current only while the test button is held, so the housing and leads stay cool during repeated checks. Because the analog needle responds instantly, there is no warm-up delay or software boot time between successive measurements.

Questions about this item

What battery voltage range does the 22YM05 tester support?

The 22YM05 tests 6V and 12V batteries with a maximum input of 16 V DC and a minimum of 0 V DC.

Will the 100 A load test work on my older 200 CCA battery?

Yes, the tester applies a 100 A load and covers a cold cranking range from 200 A up to 1,000 A.

How do I verify the analog needle is reading correctly after connecting the two leads?

Apply the load; the needle should deflect across the analog scale. If it stays at zero, check lead contact and battery voltage.
